This invention relates to buffers and perf' tains particularly to improvements in circular cloth buffers.r n

The primary object tion is to provide acloth buii'er made Of a plurality lof cloth disks secured or stitched together in such a mannerihat distortionof thexbuifer cannot occur as a result of the pull o-r drag placed upon the biasedges of the 10' disks of which the buffer is made up. Another object of the invention is to .pro

vide a cloth or fabric buffer wheel construct-y ed of a plurality of disk bodies solstitched as to form pockets adjacent theV periphery thereof in which the rouge used for `polishing operations may collect. f g

The invention will be best understood from a consideration ofthe following dethe accompanying drawings forming a part of ythe present` specification with vtheunderstanding, however, that the invention is not confined to any strict conformity with the showing of the drawings but may bev changed orinodified so long as such changes orv modifications'v mark no materialf departurefrom the salient features lof thek invention, as eX- 1 pressed in the appended claims.

Figure l is a side elevational View of a polishing wheel constructed in accordance with the present invention;r

Figure 2 is a viewfin side elevation of a modified formfoinitting the applied squares; Figure 3 is a sectional view taken upon thelineB- of Figure 2; n

Figure 4 isa transverse sectional'view taken on the line 4-1l of Figure 2.

Referring more particularly to the drawjings wherein like numerals of referencefindicate corresponding parts throughoutv the yseveral views, the numeral l indicates generally the preferred form of the buffer wheel y embodying the present invention. A modified form of this wheel is shown in Fig` kvure 2 and yis indicated generally by the num'eral 2. In each of the forms the wheel` is constructed of a pluralityof layers or disks .3 of fabric of any suitable character such as cloth or leather, cloth being preferred.

In the construction of the preferred Vform of the present invent tailed description taken in connection with 'asalathe or the like. L K

. Inthe kmodified form shown in Figure-2 shown Figure Ll after the disks have been l ylayed in superposed relation there is applied to eachface twok cloth squares 'indicated by the numerals 4 and 5. YThese c'lorthsquaresA being arranged-sothat the edges ofone eX- tendobliquely orwith respect to the edges v i of the other forming an eight-pointed star.

varrangement and as thesey squares are so' cut` that-each of the side edges is parallel with f ycertain of the threads thereof it will be read- ;ily seen'that the threads of. one square ex# tend on a bias ywith respect tothe threads of the other square and Whenthe two squares of cloth are securedV to a side of the disk',` or i l g5` wheel are arranged to extend upon a'bias wheel the threadsofthe square abutting. the

with respect to thethreads of the adjacenty wheel disk as is clearly shown in Figure l.

Each of the squares 4A and 5 of'materiall are stitched along the four edges thereof as indicated at 6 so that in the finished buffer lwheel the 'disk sections 3 will be formed to providea plurality of pockets 7 which open outwardlyfrom Vthe periphery of the wheel. These pockets catch the polishing rouge and prevent the same beingwastedthus makingv it possible lto performk extensivey polishing operations without the use of/a great amount of polishing material Y 1 .If desired the central part of the, wheel may be stitched along the lines 8, which lines Y extend parallel with the edges of the disks 4 and 5 and the central part of the 'diskis t provided with anaperture 9 to receive a holdf ing bolt or screwl by Vineans of which the disk is secured toa suitable rotating support such From the foregoing description it will Vbe seen that by applying vthe squares 4' and 5 to Lthe fabric wheels as shown in Figurel the biasedges of the disk bodies will be prevented from stretching out of shape and making the i,

-wheel distorted and'substantially the saine result is obtained hy stitching' the disks to forin the eight-pointed star design Without the use of the squares as is obtained by using the squares.

Having; thus described iny invention, what I claim is 1. A biiier Wheel, comprising a plurality of cloth disks arranged in side by side relation, applied cloth squares upon each side of the Wheel arranged to have the threads thereof extend onu bias to the threads of the ndjzieent c isli, find e second Cloth square applied over eneh of the first mentioned squares and arranged to have the threads thereof extend parallel to the threads of the adje-Cent disk,` said squares beingr secured to the Wheel by stitching` extending along each of the four edges thereof.

2. A buffer Wheel, comprising e plurality of cloth disks arranged in side by side reletion and bodies applied to each of the side faces ef the Wheel each comprising' a pair of square cloth disks arranged te ferm en eightpointed ster, each of the peints termineting;

,y at the periphery of the Wheel, and one of the squa ot' each of the bodies being1 errzingred to have the threads thereef extend on e biss to the threads of the adjacent disk.

In testimony whereof hereunto uliX my signature.
